Last night when coming back to check my G3 iMac for email, there was a Safari message box on the screen saying that I had a "world leak" and that I should report it to Apple. iMac is on DSL through D-Link wireless router. I check Sherlock AppleCare and Apple Support and can get no hits on the query. This sounds very ominous; what's up with this? Vicki vallwardt at mac.com
